Abstract

PURPOSE:To provide low cost thermal screen printing stencil paper capable of drilling of an image with low energy and excellent in phusical strength, by using an ultraviolet irradiated polypropylene as a heat-sensitive film. CONSTITUTION:Thermal screen printing stencil paper to be usable is formed by bonding a porous support layer 1 and an ultraviolet irradiated polypropylene film layer 2 by an adhesive layer 4 or by successively providing a fusion preventing layer 3 for preventing the thermal fusion of the picture line of a manuscript to the ultraviolet irradiated polypropylene film layer 2. The polypropylene film itself of this stencil paper can be prepared as a substantially extremely thin film and, as a result, if ultraviolet rays are allowed to irradiate said film, a modified thin film is formed in an extremely easy manner and drilling can be performed with low energy and a drilling property is enhanced even in the case of a thin manuscript (halftone) like pencil writing or the black and blue of an image or dye system low in carbon content and the reproducibility of the manuscript can be improved.

Natural fibers such as Manila hemp, chemical fibers such as cotton wool, vinylon, polyester, etc., and heat treatment of vinylidene chloride-vinyl chloride copolymer, polyester, etc. to a porous support such as paper or non-woven fabric or woven fabric. A sensitive film is used, and in order to create stencil paper from such base paper, the manuscript is closely attached to the film of the base paper, and then a light source consisting of infrared, visible light to near-infrared light is used: By irradiating the light containing flash isotherms, the temperature of the original document has risen to just above 74°, and the heat sensitive 74 1° area in contact with the black area is perforated by melting, agglomeration, etc.
This is done by bringing a heating element into contact with the base paper film and heating it. I (Problems to be Solved by the Invention) F) Among the conventional techniques mentioned above, for example, vinylidene chloride-vinyl chloride I-vinyl chloride copolymer film is used as a heat-sensitive film. □1・′! ″”(f!, Ldf・@K f 'j4- &C

(Function) Many conventionally used plastic films were not modified by ultraviolet irradiation and did not become easily perforated by world energy. If a polyethylene film is used, it will be modified by ultraviolet irradiation, but the thickness will be 10 μm.
Because only relatively thick materials could be produced, and because of this, it was not expected that the heat capacity would decrease much, and favorable results were not obtained.

On the other hand, according to the present invention, the polyethylene film itself can be manufactured as an extremely thin film, and as a result, when it is irradiated with ultraviolet rays, a thin film that is extremely easily modified is formed, and it can be perforated with low energy. In addition, it is possible to achieve excellent results such as improved perforation and good reproducibility of originals even with thin originals such as pencil drawings (halftone images, images with low carzene content, and dye-based black and blue). can.
